We also talked to Aaron Sharockman with PolitiFact Florida about why we're seeing so many "half true,""mostly false" or "mostly true" statements rather than a hard "true" or "false."

While arguing whether the stimulus was worth the hundreds of billions that it cost the government, Paul Ryan said, "Was it a good idea to spend taxpayer dollars on electric cars in Finland, or on windmills in China?"

Paul Ryan said this about unemployment: "They passed the stimulus. The idea that we could borrow $831 billion, spend it on all of these special interest groups, and that it would work out just fine, that unemployment would never get to 8%-- it went up above 8 percent for 43 months. They said that, right now, if we just passed this stimulus, the economy would grow at 4 percent. It's growing at 1.3."

PolitiFact Florida checked the claim that Obama promised that unemployment would never go under 8%. That rates MOSTLY FALSE.

On national security and the war in Iraq, Biden said this, "On Iraq, the President said he would end the war. Gov. Romney said that was a tragic mistake, we should have left 30,000 -- he ended it. Gov. Romney said that was a tragic mistake, we should have left 30,000 troops there."
